STEAK TENDERI Z ING APPARATUS Filed Aug. 20. 1936 I iiiyeiizbi y azzrfiey Patented Aug. 24, 1937 UNITED STATES PATENT OFFICE" 5 Claims.

' 1 cutting elements;

Still another object is an improved holding means for holding a multiplicity of safety razor blades and locking them in a cutting position;

And still another object is an improved steak l tenderizing apparatus combining the use of safety razor blades so positioned that one-half of the cutting edge of the blade together with one end may be used at a time thereby making it possible to reverse the'blades when one portion of the cutting edge becomes dulled, and other objects and novel features comprising the construction and operation of my invention will be apparent as the construction and operation is disclosed further along in my application.

In the drawing illustrating the preferred embodiment of my invention,

Fig. 1 is a plan view;

Fig. 2 is an end elevation;

Fig. 3 is a cross-section taken on the line 3-3 of Fig. l, and

Fig. 4 is a fragmentary developed plan view of the sheet-metal frame before bending, the other half of the figure being the complement of that shown. A portion of the handle has been broken away.

Referring more in detail to the drawing, l0 indicates a sheet-metal development of the body of the apparatus, the half not shown being the complement of that shown. Dot-and-dash lines A, B, C, D and E indicate the approximate position at which bends are made in the plate [0. When the bends are formed the plate l0 takes the shape shown in Figs. 1, 2 and 3. The handle 6 l is preferably bent again at l2 so that the hand of the operator is free to grasp it without coming in contact with the surface of'a steak over which the bottom l3 slides. The front top of the plate It, when bent to shape, is tilted downwardly with respect to the bottom l3, better shown in Figs.

2 and 3 and is provided with a plurality of slots Hi. It will be noted that the slots l4 extend through the vertical side wall connecting the tilted top portion l5 with the bottom portion l3 and continue part way across the bottom, as

shown in Figs. 1 and 3. The extreme edge of the tilted portion 15 may be folded over, as indicated at l 6. The side extension members ll which are located on each side of the plate ID are folded up on the line C to form a right-angle with the bottom portion I 3. These extension membersare further provided with a combined vertical and horizontal slot indicated respectively at l8 and I9.

Safety razor blades 20 are provided having notches 2| located in the upper portion ofthe edge of each end. The notch on one end of each blade is positioned against the end of. the slots l4 adjacent the folded side of the top portion l5.

A flat horizontally disposed blade bar 22, preferably having a rounded edge engages the notches on the opposite end edges of the blades 20, and is held in position in the horizontal slots l 9 inthe extension members ll. When the blades 20 and bar 22 have been assembled together a' vertical locking bar 23 is slid into place in the vertical slots l8 thereby locking the bar 22 against move-. ment and tightly binding the bladesZfl in the slots M.

It will be noted that the outer cutting corners of the blades 20 are lower than the under surface of the bottom 13 so that when the apparatus is 25 drawn across a steak surface the low corner and a portion of the blade edge engages the fibrous surface of the steak and produces a series of cuts in a parallel direction. When the steak surface is fully cut all over its surface in one direction 30 either the apparatus or the steak may be turned at ninety degrees and another parallel series of cuts may be made thereby severing the near surface fibers at regular intervals and at rightangles. 35

It is understood that the amount of tilt given the portion I5 of the plate Ill may vary to suit conditions, size and type of blade used, and it is to be understood that I may vary the size and proportion of the apparatus, the number of cut- 40 ters, or material from which the apparatus is constructed within wide limits without departing from the spirit of the invention.

Having thus described my invention, what I claim as new is:

1. A holder for a plurality of blades of the type having a notch in each end edge, comprising a section having a plurality of blade-receiving slots formed therein, a second section extending outwardly from an edge of said first-named 50 section at a substantial angle thereto and including an integral marginal portion at the outer edge thereof, said slots being continued in said second section and terminated by said marginal portion, brackets mounted on one of said sec- 55 tions, and a blade bar removably supported by said brackets adjacent to said first-named section, whereby said marginal portion and said blade bar will engage the notches of the outer and inner end edges respectively of a blade disposed in one of said slots.

2. A steak tenderizing apparatus comprising a slotted blade holding member, the said member having an elevated portion connecting with a lower base portion, the said slots extending in parallel relation from a marginal side of said elevated portion continuously across to the other side of said portion and terminating in said lower base portion, slotted brackets attached to opposite side edges of said blade holding member adjacent the lower base portion, and a locking bar adapted to engage through said slotted brackets for the purpose of locking cutter blades in said slots of the elevated portion, the said blades being provided with notches located in the end edges of the blades and said notches being adapted to engage against one of said locking bars at one end and against the end of one of said slots in said elevated portion.

3. A steak tenderizing apparatus comprising a holder for a plurality of thin blades having a notch located in each end edge, said holder being provided with an upper slotted and tilted portion and a lower base portion, the said tilted portion being connected with said lower base portion by means of a connecting end portion, the said slots being parallelly positioned in said tilted portion and continuing through said end portion and into said base portion, the ends of said slots being terminated in an outer marginal portion of said tilted portion and in a marginal portion of said base portion, brackets attached to opposite sides of said holder adjacent said end portion and being further provided with T shaped slots, a blade bar adapted to engage the notches on one end of said blades when said blades are mounted in said slots of the tilted portion, and a locking bar adapted to lock said blade bar in place, both of said bars being supported in said T shaped slots in said brackets, the notches on the opposite end of said blades being adapted to engage against the inner ends of the slots in the outer marginal portion of the tilted portion.

4. A steak tenderizing apparatus for use with a plurality of cutter blades having notched end edges, said apparatus comprising a slotted holder having an upper tilted portion and a lower base portion and a substantially vertical connecting wall connecting said base with said tilted portion, the said slots terminated in marginal portions on said tilted portion and said base and being continuous therebetween, and brackets attached to the sides of said apparatus having slots located therein for the purpose of receiving a blade locking bar, said bar being adapted to engage the notch on one of said blades, the notch on the said opposite end of the blade engaging in one end of one of said slots in said tilted portion.

5. A steak tenderizing apparatus comprising in combination a plurality of rectangular cutting blades having notches located in their end edges, a blade holding frame, said frame comprising a guiding base portion and an elevated tilted portion, continuous blade slots parallelly disposed to each other and extending from a marginal edge on said tilted portion to a marginal end in said base portion, brackets attached to said frame, slots located in said brackets, and a horizontal blade locking bar adapted to engage in a slidable manner in said bracket slots, one end of said bar being adapted to engage in the notch on one end of said blade, the notch on the other end of said blade being adapted to engage the end of the slot in said tilted portion.
